I have just ordered the RX100 and Nauticam housing, but seriously considered the Ikelite as my current rig is an Ikelite with Fuji e900. I've been using S&S strobe in slave mode triggered by the camera's internal flash (blocked by diverter panel that attaches around the lens port) and S&S fiber optic cable. I have always used strobes in manual setting mode, never in TTL. If I could see better, and had more time to dive, this set up can take fabulous photos. Others with same set up have been very successful. I remain unconvinced that TTL matters for u/w strobes if you already know how to shoot with manual camera settings.
